SUBJECT:

Update to Evaluations Described Response to Request for Additional Information 15(a)

Reactor Vessel Internals Aging Management Program Plan Arkansas Nuclear One, Unit 1 Docket No. 50-313 License No. DPR-51

Dear Sir or Madam:

Entergy Operations, Inc. (Entergy) submitted the Arkansas Nuclear One, Unit 1 (AN0-1)

Reactor Vessel Internals Aging Management Program Plan (Reference 1) to fulfill a commitment made as part of the AN0-1 License Renewal Application. The plan identified the reactor vessel internals components that must be included for aging management review and identified the augmented inspection plan for those components.

The NRC issued a Req1,1est for Additional Information (RAI) via Reference 2. Reference 3 provided the Entergy responses to the RAI, with a commitment to provide the requested evaluations associated with RAI 15(a) by September 2015. RAI 15 is related to the Applicant I Licensee Action Item 7 of the NRC Staff Safety Evaluation (SE) for MRP-227-A. This action requires the development of plant-specific analyses to demonstrate reactor vessel internal components that may be fabricated from cast austenitic stainless steel, martensitic stainless steel or precipitation hardened stainless steel, will maintain their functionality during the period of extended operation.

Reference 5 provided the response to RAI 15(a). The Reference 5 response included both a proprietary and non-proprietary vers.ion of AREVA Document ANP-3417NP, Revision 0, MRP-227-A Applicant I Licensee Action Item #7 Analysis for Arkansas Nuclear One Unit 1.

Following initial review, the NRC questioned some of the proprietary markings (also called "redactions") in the report. Entergy and AREVA subsequently completed further review of the report in an attempt to minimize the amount of material to be redacted. Attachment 1 is the proprietary version of AREVA Document ANP-3417P, updated to minimize redactions. The respective non-proprietary version of the AREVA document, ANP-3417NP, is included in Attachment 2.

Attachment 1 to this letter contains proprietary information Attachment 1 is withheld from public disclosure per 10 Ci=R 2.390.

1CAN051605 Page 2of3 AREVA requests that the proprietary information be withheld from public disclosure in accordance with 10 CFR 2.390. AREVA has provided Entergy with authorization to provide the proprietary information. An affidavit by the information owner, AREVA, supporting the request for non-disclosure is provided in Attachment 3. Therefore, Entergy requests that Attachment 1 of this submittal be withheld from public disclosure in accordance with 10 CFR 2.390.

The evaluations presented in this submittal were developed by AREVA for both AN0-1 and Oconee 1, 2 and 3, and are similar to those that were approved by the NRC in the SE for the Oconee station (Reference 4). It should be noted that Reference 4 addresses other Applicant I Licensee Action Items in addition to Item 7.

The regulatory commitment included in Attachment 4 of the original Entergy response to RAI 1S(a) (Reference 5) is repeated in the letter for completeness. This commitment is listed in of this letter.

In accordance with 10 CFR 50.91 (b)(1 ), a copy of this application is being provided to the designated Arkansas state official.

If you have any questions or require additional information, please contact me.
